$\star\:\sf Valency \:\star$

»» Valency is the number of electrons that is needed by an atom to become stable or in other words full its outer shell with the maximum number of electrons

»» Valency =8 - Valence electrons

»» But the above formula doesn't hold true if the valence electron is 1,2 or 3

»» So if an atom has its valence electron as 1,2 or 3 then it's Valency will also be 1,2 or 3 respectively

»» Atoms with zero Valency is called as noble gas and these doesn't react with each other
